“…Based on the idea given in Ref. [9], Osauskas et al [10] proposed a linearised small-signal analytic model of the HVDC converter in the frequency domain suitable to assess the steady-state harmonic waveforms distortions. The model describes the converter operation in terms of both base and distorting cases as well as switching instant modulation.…”

“…However, with the development of modern multivariable control system frequency domain theory, frequency domain analysis method gets more and more attentions by the electricity workers in recent years, and then achieves further development. The frequency domain analysis model of power system small signal stability, including the high-voltage direct current (HVDC), is built in [28]. And in [29], it is applied to the robust stability analysis of power systems.…”

The integration of large amount of wind power into a power system imposes a new challenge for the secure and economic operation of the system. It is necessary to investigate the impacts of wind power generation on the dynamic behavior of the power system concerned. This paper investigates the impacts of large amount of wind power on small signal stability and the corresponding control strategies to mitigate the negative effects. The concepts of different types of wind turbine generators (WTGs) and the principles of the grid-connected structures of wind power generation systems are first briefly introduced. Then, the state-of-the-art of the studies on the impacts of WTGs on small signal stability as well as potential problems to be studied are clarified. Finally, the control strategies on WTGs to enhance power system damping characteristics are presented.

“…The approach used is similar to that used for the HVdc converter [9], which has been used as the basis for both harmonic and small-signal transient studies [10], [11]. The proposed STATCOM model can be used within the same framework.…”

A linear frequency-domain model of a static VAr compensator (STATCOM) is presented. Large signal transfers are derived to determine characteristic harmonics, and small-signal transfers are derived to determine noncharacteristic harmonics. Harmonic transfers are also derived for phase-locked loop and reactive power controls, and the response of a controlled STATCOM to a negative sequence fundamental frequency imbalance is demonstrated. As the model is linear, it is very computationally efficient, and is well suited to analysis of large networks with a number of similar connected FACTs devices. The importance of including full control dynamics for harmonic analysis is also clearly shown.
